How can you tell if you have a warped bullet mould?
Ask it if likes to watch Pee Wee Herman movies?
sorry, just a little joke... I have an old Lyman 38 wadcutter mould that fell off my bench while casting hot and landed on one corner of one of the blocks. When the mould cooled off, it fit together perfectly and looked fine other than a ding in where the block hit the concrete. But when it got heated up to casting temps....the bullets would come out with flashing around the nose of the bullets. If you held the mould together at casting temps, you could see where the mould halves didn't seat together as they did when cold...or before I dropped it. So both hot and cold, see how the faces of the blocks line up, see how the pins fit into the mortises...
